Abstract (en)
Provided are a production process for a rotating hub type paper-plastic product, and a device utilizing the production process. The device comprises: a rotating hub forming unit (2), which can continuously generate a primary blank; an array unit (21), which forms, by means of an uplink lifting mechanism (211), a downlink descending mechanism (212), an uplink array channel and a downlink array channel, a carrier capable of moving in a circulating and reciprocating manner for a profiling jig plate (213) moving in a reciprocating manner thereon; a left forming area unit (22) and a right forming area unit (23) which are respectively arranged at two sides of the array unit and are internally provided with machining areas for a plurality of hot-pressing shaping mechanisms and a plurality of edge cutting mechanisms for use in hot-pressing shaping and edge cutting of the primary blank; a first transfer mechanism (24) and a second transfer mechanism (25) which stretch across the array unit (21) and the left and right forming area units (22, 23) and are provided with a plurality of conveying molds (251) in a suspended manner, so that the primary blank can be transferred; two discharging conveyors (26) which are respectively arranged on the outermost sides of the left and right forming area units; and two defective product conveyors (27) which are arranged between each of the left and right forming area units and each of the discharging conveyors for outputting a defective product which is subjected to screening.
